Project FEVER (2019-2023)

Forest vulnerability to extreme and repeated climatic stress
© Shekhar et al. 2024 STOTEN

The frequency and severity of heat events are increasing across Europe: by the end of the 21st century, countries in central Europe will experience the same number of hot days as are currently experienced in southern Europe. The uncertainty of how forest trees react to increased temperatures and heat stress is also related to the fact that ecophysiological reactions vary across species, sites and regions, biome types, and prevailing climatic conditions, which makes their realization in land-​atmosphere models challenging. To improve the understanding of forest-​climate interactions, a multi-​scale approach is needed, that is able to investigate the ecosystem as a whole, to be able to predict the degree to which the forest ecosystem is susceptible to adverse climatic stress impacts. The project FEVER linked physiological leaf, tree, and root processes with the ecosystem-​level fluxes of water vapor, to understand the contribution of vegetation, and the direction in which forest-​climate interactions will be affected by future changes in climate.
